I've uploaded my R Shiny app (using shinyMobile package) to Google Cloud Run using a Dockerfile, and am finding that the date returned by f7DatePicker doesn't match the value on the widget itself. So if I put in 2021-08-02, the actual date it returns (looking at the 'input$x' value) is 2021-08-01, even though the date displayed on the widget is 2021-08-02.
HOWEVER, it appears that this only occurs for users in particular timezones. I'm currently in New Zealand, and am finding that this issue is occurring for the mobile app for NZ based users; however, when I try running the app on a server in the US (i.e. via Browserstack), the date is correctly returned. BUT when I run the app locally on my desktop (in New Zealand), I don't have this issue. So I'm not sure if the issue is at the server end or at the client end.
It's possible that the issue is caused by daylight savings - see this link - but my local server runs fine, so if this were the case, it would have to be the interaction between Cloud Run and mobile somehow.
Here's the code I'm using to calculate client_time and time_zone_offset (based on this link:)
Javascript:
HTML('<input type="text" id="client_time" name="client_time" style="display: none;"> '),
HTML('<input type="text" id="client_time_zone_offset" name="client_time_zone_offset" style="display: none;"> '),
tags$script('
$(function() {
var time_now = new Date()
$("input#client_time").val(time_now.getTime())
$("input#client_time_zone_offset").val(time_now.getTimezoneOffset())
});')
Shiny: (in server.r)
client_time <<- as.numeric(input$client_time) / 1000 # in s
time_zone_offset <<- as.numeric(input$client_time_zone_offset) * 60 # s from GMT
curr_datetime <<- as_datetime(client_time - time_zone_offset)
Any ideas what the issue could be?
Thanks a lot

I have a javascript and Powershell script allowing to detect a usb plug, and which shows me a pop up. Indeed, my script only detects new usb keys that have not yet been plugged into the system. That's why I would like to delete the usb key history from my computer, like USB OBLIVION does, in order to have as a new connection to each usb plug.
I don't see what I need to add to my script... I have already tried deleting the content of:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB
Thanks
You could try these, but don't forget to wipe the from them other 3 paths as well
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\SWD\WPDBUSENUM
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Portable Devices\Devices\
You could also consider using WMI Event subscriptions, this works whatever the usb key is already known or not, but do not clear the registry :
to detect usb plug :
Register-CIMIndicationEvent –Query `
"Select * From __InstanceCreationEvent Within 1 Where TargetInstance IsA 'Win32_LogicalDisk'" `
–SourceIdentifier "WMIInsert" –Action { Write-Host `
"$($Event.SourceEventArgs.NewEvent.TargetInstance.Name) plugged!`n" }
to detect usb ejection :
Register-CIMIndicationEvent –Query `
"Select * From __InstanceDeletionEvent Within 1 Where TargetInstance IsA 'Win32_LogicalDisk'" `
–SourceIdentifier "WMIEject" –Action { Write-Host `
"$($Event.SourceEventArgs.NewEvent.TargetInstance.Name) ejected!`n" }
Within 1 means to detect every one second. Depending on your needs, you can configure Within 30 for example to look it for every 30 seconds (every plug or ejection in the meantime are captured as well).
the -Action parameter let you do whatever you want since this is a scriptblock (In the example I provided the event is only displayed to the console).
And do not forget that StackOverflow is not a free coding service, so next time, please share the piece of code where you have got a problem or a bug.
Update:
Please see the answer noted below as, ultimately, the problem had nothing to do with jsquery.
=============
Issue:
I submit an object to jquery to convert into a serialized string that will become part of a "POST" request to a server, and the data returned from the serialization request is different than the data sent on many occasions.
An example:
The JavaScript code that implements the server POST request:
function send_data(gpg_data) {
var query_string;
query_string = '?' + $.param(gpg_data, traditional = true);
console.log('gpg_data =', gpg_data)
console.log('query_string =', query_string);
$.post(server_address + query_string);
return;
}
This is the structure sent to the jquery param() function.
(copied from the browser console in developer mode.)
gpg_data =
{controller_status: 'Connected', motion_state: 'Stopped', angle_dir: 'Stopped', time_stamp: 21442, x_axis: 0, …}
angle_dir: "Stopped"
controller_status: "Connected"
force: 0
head_enable: 0
head_x_axis: 0
head_y_axis: 0
motion_state: "Stopped"
time_stamp: 21490
trigger_1: 0
trigger_2: 0
x_axis: 0
y_axis: "0.00"
. . . and the returned "query string" was:
query_string = ?controller_status=Connected&motion_state=Stopped&angle_dir=Stopped&time_stamp=21282&x_axis=0&y_axis=0.00&head_x_axis=0&head_y_axis=0&force=0&trigger_1=1&trigger_2=1&head_enable=0
The data received by the server is:
ImmutableMultiDict([('controller_status', 'Connected'), ('motion_state', 'Stopped'), ('angle_dir', 'Stopped'), ('time_stamp', '21282'), ('x_axis', '0'), ('y_axis', '0.00'), ('head_x_axis', '0'), ('head_y_axis', '0'), ('force', '0'), ('trigger_1', '1'), ('trigger_2', '1'), ('head_enable', '0')])
For example, note that "trigger_1" returns 1 when the data sent to it is a zero.
I have tried setting the query to "traditional = true" to revert to an earlier style of query handling as some articles suggested - which did not work. I tried this with jquery 3.2 and 3.6.
I am not sure exactly how jquery manages to munge the data so I have no idea where to look.
I have looked at my script and at the unpacked jquery code, and I can make no sense out of why or how it does what it does.
Any help understanding this would be appreciated.
P.S.
web searches on "troubleshooting jquery" returned very complex replies that had more to do with editing e-commerce web pages with fancy buttons and logins than with simply serializing data.
P.P.S.
I am tempted to just chuck the jquery and write my own serialization routine. (grrrr!)
===================
Update:
As requested, a link to the browser-side context.
To run: unpack the zip file in a folder somewhere and attach an analog joystick/gamepad to any USB port, then launch index.html in a local browser. Note that a purely digital gamepad - with buttons only or with a joystick that acts like four buttons - won't work.
You will want to try moving joystick axes 1 and 2, (programmatically axes 0 and 1) and use the first (0th) trigger button.
You will get a zillion CORS errors and it will complain bitterly that it cannot reach the server, but the server side context requires a GoPiGo-3 robot running GoPiGo O/S 3.0.1, so I did not include it.
Note: This does not work in Firefox as Firefox absolutely requires a "secure context" to use the Gamepad API. It does work in the current version of Chrome, (Version 97.0.4692.99 (Official Build) (64-bit)), but throws warnings about requiring a secure context.
Please also note that I have made every attempt I know how to try to troubleshoot the offending JavaScript, but trying to debug code that depends on real-time event handling in a browser is something I have not figured out how to do - despite continuous searching and efforts. Any advice on how to do this would be appreciated!
======================
Update:
Researching debugging JavaScript in Chrome disclosed an interesting tidbit:
Including the line // #ts-check as the first line in the JavaScript code turns on additional "linting" (?) or other checks that, (mostly) were a question of adding "var" to the beginning of variable declarations.
However. . . .
There was one comment it made:
gopigo3_joystick.x_axis = Number.parseFloat((jsdata.axes[0]).toFixed(2));
gopigo3_joystick.y_axis = Number.parseFloat(jsdata.axes[1]).toFixed(2);
I could not assign gopigo3_joystick.y_axis to a string object, (or something like that), and I was scratching my head - that was one of the pesky problems I was trying to solve!
If you look closely at that second line, you will notice I forgot a pair of parenthesis, and that second line should look like this:
gopigo3_joystick.y_axis = Number.parseFloat((jsdata.axes[1]).toFixed(2));
Problem solved - at least with respect to that problem.
I figured it out and it had nothing to do with jquery.
Apparently two things are true:
The state of the gpg_data object's structure is "computed", (snapshot taken), the first time the JavaScript engine sees the structure and that is the state that is saved, (even though the value may change later on). In other words, that value is likely totally bogus.
Note: This may only be true for Chrome. Previous experiments with Firefox showed that these structures were updated each time they were encountered and the values seen in the console were valid. Since Firefox now absolutely requires a secure context to use the gamepad API, I could not use Firefox for debugging.
I was trying to be "too clever". Given the following code snippet:
function is_something_happening(old_time, gopigo3_joystick) {
if (gopigo3_joystick.trigger_1 == 1 || gopigo3_joystick.head_enable == 1) {
if (old_time != Number.parseFloat((gopigo3_joystick.time_stamp).toFixed(0))) {
send_data(gopigo3_joystick)
old_time = gopigo3_joystick.time_stamp
}
}
return;
}
The idea behind this particular construction was to determine if "something interesting" is happening, where "something interesting" is defined as:
A keypress, (handled separately)
A joystick movement if either the primary trigger or the pinky trigger is pressed.
Movement without any trigger pressed is ignored so that if the user accidentally bumps against the joystick, the robot doesn't go running around.
Therefore the joystick data only gets updated if the trigger is pressed. In other words, trigger "release" events - the trigger is now = 0 - are not recorded.
The combination of these two events - Chrome taking a "snapshot" of object variables once and once only, (or not keeping them current) - and the trigger value persisting, lead me to believe that jquery was the problem since the values appeared to be different on each side of the jquery call.

And after this update 1 script stoped working because it tries to disable view picker.
function setDefaultView(viewId, fiedlId) {
Xrm.Page.getControl(fiedlId).setDefaultView(viewId);
**parent.document.getElementById(fiedlId).attributes.disableviewpicker.value = "1";**
}
I tried this options I found online but it seems none of them are supported
function setDefaultView(viewId, fiedlId) {
Xrm.Page.getControl(fiedlId).setDefaultView(viewId);
var partnerField = Xrm.Page.getControl(fiedlId);
partnerField.SetParameter("disableViewPicker", "1");
}
Also when i try to debug this no longer returns information
Is there a new way to turn on/off the view picker with JS?
I cant find any recent information about this subject.
UPDATE:
What i need is, if that source campaign is selected, to disable view picker in that lookup field.
Thanks in advance

I'm writing a simple Automator script in Javascript.
I want to send a key-code(or key-storke) to an OS X application that is not in front.
Basically, I want to run this code and do my things while the script opens a certain application, write text, and hit enter - all of this without bothering my other work.
I want something like this:
Application("System Events").processes['someApp'].windows[0].textFields[0].keyCode(76);
In Script Dictionary, there is keyCode method under Processes Suite.
The above code, however, throws an error that follows:
execution error: Error on line 16: Error: Named parameters must be passed as an object. (-2700)
I understand that the following code works fine, but it require the application to be running in front:
// KeyCode 76 => "Enter"
Application("System Events").keyCode(76);
UPDATE: I'm trying to search something on iTunes(Apple Music). Is this possible without bringing iTunes app upfront?
It's possible to write text in application that is not in front with the help of the GUI Scripting (accessibility), but :
You need to know what UI elements are in the window of your specific
application, and to know the attributes and properties of the
specific element.
You need to add your script in the System Preferences --> Security
& Privacy --> Accessibility.
Here's a sample script (tested on macOS Sierra) to write some text at the position of the cursor in the front document of the "TextEdit" application.
Application("System Events").processes['TextEdit'].windows[0].scrollAreas[0].textAreas[0].attributes["AXSelectedText"].value = "some text" + "\r" // r is the return KEY
Update
To send some key code to a background application, you can use the CGEventPostToPid() method of the Carbon framework.
Here's the script to search some text in iTunes (Works on my computer, macOS Sierra and iTunes Version 10.6.2).
ObjC.import('Carbon')
iPid = Application("System Events").processes['iTunes'].unixId()
searchField = Application("System Events").processes['iTunes'].windows[0].textFields[0]
searchField.buttons[0].actions['AXPress'].perform()
delay(0.1) // increase it, if no search
searchField.focused = true
delay(0.3) // increase it, if no search
searchField.value = "world" // the searching text
searchField.actions["AXConfirm"].perform()
delay(0.1) // increase it, if no search
// ** carbon methods to send the enter key to a background application ***
enterDown = $.CGEventCreateKeyboardEvent($(), 76, true);
enterUp = $.CGEventCreateKeyboardEvent($(), 76, false);
$.CGEventPostToPid(iPid, enterDown);
delay(0.1)
$.CGEventPostToPid(iPid, enterUp);
Our lab recently got an Agilent Bravo pipetting robot (it precisely dispenses tiny quantities of liquid for doing rapidly doing many biology or chemistry experiments). Apparently the glue language for extending the software that controls the robot is Javascript! I know, right?
Anyway, for the robot to be useful, we have to be able to retrieve information about the samples it's handling but every example I can find for sending queries in Javascript depends on PHP and usually the assumption that the script is running in a web-browser.
Is there some way to wrap a command-line mysql or is there already some library or utility that does this? The OS we're running is Windows 7.
Wow, thanks for the quick and useful answers.
In addition, I found a platform-specific answer: http://www.velocity11.com/techdocs/helpsystem/vworks_ug/usingjavascriptinvworks.html
Long story short, VWorks (control software for Agilent's equipment) has a run() global function that does exactly that. But, the above answers are probably more useful to this site than my own is, because they are relevant to a broader range of problems, so thanks again.
"sending queries in Javascript depends on PHP"
no it doesn't.
Just send retreive data(json) using ajax, I'd use http://api.jquery.com/jQuery.ajax/.
Yes, you can use ADO with Javascript on Windows to access various data sources. Search for "jscript ado" and you will get lots of information on this, e.g.:
// path to database
var DBpath="\\\\Server\\Path\\myDB.mdb"
// set up a few object constants
var adLockReadOnly=1
var adOpenForwardOnly=0
var adCmdText=1
// create and open a new connection (MSAccess)
var cnn=new ActiveXObject("ADODB.connection")
cnn.Provider = "Microsoft.Jet.OLEDB.4.0;Data Source=" + DBpath
try
{
cnn.open
}
catch(err)
{
// could not open connection
// view details in err.Description and err.Number
return 0
}
//open a read only recordset
var rs = new ActiveXObject("ADODB.Recordset")
try
{
rs.Open("Select * from myTable", cnn, adOpenForwardOnly, adLockReadOnly)
}
catch(err)
{
// could not open recordset
return 0
}
while(!rs.EOF)
{
// do something
rs.movenext
}
rs.close
Update:
According to info here, you can develop plugins using Visual Studio/C#. Maybe that is of some use? You could write a plugin to send the data somewhere...
